What we do not do

  • We do not sell, rent or trade personal data.

  • We do not track you across other websites.

Our free tools

The calculators and assessments on this site run entirely in your browser. Figures you enter are not transmitted to us, not stored on any server, and not retained once you close the page. If a tool offers to email you a result, that email address is used for that one message and nothing else.

Cookies and analytics

No analytics or advertising cookie is set until you choose to accept one. Until then, measurement is disabled by default. You can change your choice at any time by clearing this site’s data in your browser. Full detail is in our cookie policy.

Who else processes your data

We use a small number of service providers to host this website, deliver email and, if you consent, produce anonymous usage statistics. They act on our instructions and may not use your data for their own purposes. Where a provider processes data outside the European Economic Area, that transfer is covered by the European Commission’s standard contractual clauses or an adequacy decision.

Your rights

Under the GDPR you can ask us to:

  • give you a copy of the personal data we hold about you;
  • correct anything inaccurate;
  • delete it;
  • restrict or object to how we use it;
  • send it to you or another controller in a portable format;
  • withdraw consent at any time, without affecting what we did before you withdrew it.

Write to info@isdifoundation.com and we will respond within one month. If you are not satisfied, you may complain to the Bulgarian Commission for Personal Data Protection (Комисия за защита на личните данни) or to the supervisory authority where you live.

Changes

If we change this policy we will update the date above and, for anything significant, say so on the site.
